[ Upstream commit 73b5a5c00be39e23b194bad10e1ea8bb73eee176 ]
It seems a copy&paste mistake that suspend callback removes the GPIO device. There is no counterpart of this action, means once suspended there is no more GPIO device available untile full unbind-bind cycle is performed. Remove suspicious GPIO device removal in suspend.
